HMASTER - The modern, privacy-first HTTP Header Manager for Chrome

by•
Hey Product Hunt! 👋 I'm Jonatan, the creator of HMASTER. As a web developer, I often found myself needing to tweak HTTP headers—whether to bypass CORS issues during development, test APIs with different Authorization tokens, or simulate mobile devices. I felt that existing tools were either stuck in the past (clunky UI), relied on outdated APIs that slowed down the browser, or were just too complex for quick tasks.
